What this work involves
Assess the roof structure and waterproofing before choosing a green roof. Consider the weight of the complete system.
- Capacity and build-up
- Drainage and perimeter zones
- Planting and maintenance
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Test new facade material against substrate and existing details.
What the drawing needs to explain
Mark intact, damaged and unassessed areas on photographs. Add the old-to-new junction detail with proposed materials and treatment.
Allow for later maintenance
Keep product information and photographs of the assessed substrate. They support later inspection without reconstructing the original repair decision.
Which trade-off matters?
Full renewal creates a uniform appearance, while targeted repair preserves more existing material. Compare both using a sample area and assess technical compatibility too.
Cost factors for this service
Costs depend on area, roof adaptations, system and access. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for green & sedum roofs. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging green & sedum roofs?
Not every flat roof is immediately suitable. Establish whether the structure, waterproofing and drainage can support the proposed system.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
